1// nx_site_publish_lib.nx -- ARTIFACT-PUBLISH, LIBRARY half (sp_main dispatcher) capability (closes the coverage BUILD-queue gap "artifact-publish";
2// retires the ssh-cat content lane for pages). Places a NAS-local file into the live sites docroot the
3// SAFE way, composing the proven IO layer:
4//   publish <src-file> <site> <relpath>  ->  sites/<site>/<relpath>
5//     - ATOMIC placement via fsx_write (tmp+fsync+rename -- a browser never sees a torn page)
6//     - PRIOR VERSION PRESERVED: an existing target is first copied to <relpath>.prev (rename-not-delete
7//       doctrine; one-deep history -- generated artifacts, git holds sources)
8//     - DENY BY CONSTRUCTION (fsx_write_denied: secrets/device-ns/allowlist) PLUS path-traversal refusal:
9//       any ".." segment or absolute site/relpath is DENIED (an MCP caller must not escape the docroot)
10//   The organ prints the live URL; verification is the SEPARATE browser-grade organ (composition, not a
11//   built-in fallback): run nx_page_verify <url> from a WAN vantage (on-NAS bare-domain fetches hit DSM --
12//   the documented trap). The publish->verify recipe is the contract; this organ does the placement half.
13//     - THE PUBLISH GATEWAY (F763 second half, wired 2026-07-30): for a site listed in
14//       knowledge/pub_sites.conf, a <relpath> absent from that site's publishing REGISTRY -- or
15//       carrying a non-publishable status (withdrawn/redirect/debris) -- is REFUSED. This is the
16//       half that makes "random and arbitrary" impossible instead of merely visible: nx_pub_desk
17//       stated the rule in 2026-07-19 and its own header recorded that enforcement inside the
18//       publish organ was never wired, so anything could be dropped into any docroot and become
19//       site truth. MEASURED before wiring: 54 pages served on nishifamily.com were in NO registry.
20//       Sites NOT in the site table publish UNGATED (with a warning) -- onboarding is a config row,
21//       and a control that refuses everything on day one is a control someone disables by lunchtime.
22// exit: 0 ok | 2 usage | 3 src absent | 4 io | 5 DENIED  license_tier: ORIGINAL
